WAX-SWATING APPARATUS.

Application filed November 13, 1920. serial No. 423,869.

To all whom it may concern:

Be it known that we, CARL S. DICKENS, THoMAs E. SCHLEY, and JOHN W.NnwroN, citizens of the United States, residing at Beaumont, in thecounty of Jefierson and State of Texas, have invented new and usefulImprovements in Wax-Sweating Apparatus, of which the following is aspecification. 1

This invention relates to an apparatus intended primarily for thefractional separation, by sweating, of crude, slack, intermediate andother types of paraffin-wax and like mixtures of substances havingdifierent melting points. The invention has as its object the provisionof an apparatus in which may be expeditiously and economically conducteda continuous wax sweating process as above described.

Another object of the invention is the provision of an apparatus whichis adaptable to the sweating/of all types of parafiin-wax without in anyway modifying the structure of the apparatus;

In its broad aspect the invention contemplates the provision of achamber divided into a plurality of compartments each compartme-nthaving heating means which may be regulated to bring the temperature ofthe compartment to a desired predetermined degree. f The Wax isconducted through the chamber upon an endless, foraminous belt beneathwhich, in such compartment, are located oil receiving receptacles toreceive the The invention also contemplates the provision of an improvedmeans for charging the apparatus so that the 'wax will be placed uponthe belt evenly and uniformly.

Other features and objects of the invention, such as a provision ofmeans for readily determining the temperature within each of thecompartments and means for preventing the .passa e of heat from onecompartment to the ot er, will become obvious from a reading of thefollowing detail description in connection with the accompanyingdrawings, wherein there is shown one specific form which our inventionmay take.

In these drawin s: 1

Fig. 1 is a longitudinal sectional view of one end of the apparatus,

Fig. 1 is a similar view of the other end of the apparatus, 7

Fig. 2, is a horizontal sectional view on the line 2-2 of Figs. 1 and 1the central portion of the apparatus being shown as broken away for lackof space,

Fig. 3 is a transverse section on the line 3-3 of Fig. 1,

Fig. 4 is a detail view showing the feed roll drive,

Fig. 5 isanother detail view showing the 1113511161 of connecting thechain to the belt, an I Fig. 6 is a detail view showing the constructionof the chain links.

Referring to the drawings more in detail,

10 indicates a sweating chamber constructed of concrete, brick or othersuitable material and supported upon longitudinally extending beams 11and transverse beams 12, which beams, together with the verticalsupports 13, afford a foundation for the sweating chamber. The chamberis divided by means of partitions 14 into a plurality of compartments10?, 10 10, 10 eto., it being understood that the chamber may be of anydesired size and may contain any given number of compartments.

Each partition 14 has an opening =15 through which extend a plurality ofparallel tracks 17 extending through all of the compartments from oneend of the chamber to the other and serving to support an endless belt18 constructed preferably of perforated steel plates. The belt 18travels through the openings in the partitions forming the severalcompartments and also traverses drums 19 and20 at the front and rearends, respectively, of the chamber. The edges-bf the belt are supportedby means of idler pulleys 21 rotatably mounted in depending brackets 22supported from the irders 23 embodied in the ceiling construction of thechamber.

The specific character of the belt will be hereinafter referred to morein detail for it is thought well, at this point, to refer to the factthat each of the compartments is rovided with an entrance opening 24 inw rich is located a closure 25 thus permitting access to each of thecompartments for inspection and repair of the apparatus.

Within the compartments are placed oil receptaclet .26 the receptaclesbeing, of

ice

- belt, and deflectors 27 being provided adjaindividual compartments.

, partment so that the heat in the latter may be determined withoutentering the comtraversed by a chain 47 wh ch also traverses cent eachedge of the several receptacles to direct the falling oil to the pans.-The oil may be removed from the pans either by drain pipes which connectwith each of the receptacles, or the individual receptacles, or

the individual receptacles may be removed when they become filled. lhereceptacles or pans 26 ma be supported upon longitudinally exten ingbeams 28 below which beams may be located the heating means for the Inthe form of the device illustrated the-heating means is shown as beingsteam containing coils 29, several coils being provided for eachcompartment. If des1red a thermostatic valve 30 may be located adjacenteach com-part ment so that the heat therein may be readily regulated tothe desired degree.

These valves may be manually regulated or, as shown in the drawings, maybe automatically operated by means of a heat responsive element 3Olocated in each compartment, it being understood that any suitable'typeof thermostatic valve may be used for the purpose. Above eachcompartment are located thermometers 31. projecting into eachcompartment.

By an inspection of Figs. 1 and 1 it will be observed that adjacent theopenings 14 in the several partitions and to the latter are securedflexible curtains 32. The lower edges of these curtains rest upon thesursired degree may be maintained in the compartments severally andcollectively, that means is provided for quickly determining thetemperature within each of the com.- partments, and that quickinspection of any given compartment may be made by reason of therovision of the entrance openings in the sides of the compartments.

less belt, any suitable material, such as wire mesh, may be used, butthe construction shown in the drawings has been found to be" preferable,the illustrated construction comprising a plurality of comparativelynarrow perforated metal plates 33 eirtending trans-.

versely of the belt and held'together edge to edge by means of a pair'of endless chains 34 secured to the under face of the belt adjacent itsvlateraledges. .By reference to Figs. 5 .and 6 it will be noted that thechains are formed from a plurality of links, each link bein rovided.with a pair of laterally ap aratus. a Referring to-the construction ofthe end-' neaefiar extending ears 36 having openings therein throughwhich are passed bolts 37 ektend= ing through the belt plates 33 andthus rigidlysecuring the chains to the plates. Each of" the links isalso'formed w1th an end hook 38 which engages the adj acent link whichmesh with the chains upon thetraveh ing belt.

Any suitable means may be used to charge I the belt, but in theillustrated embodiment of the invention there is shown a roller 40mounted above the drum 19 in bearings 41 suitably positioned above andat each end of a waxpan 42, the pan and the roller 40 being so relatedthat the periphery of the roller extends into the pan. At one side ofthe roller is located a scraper 43 which, upon rotation of the roller,removesthe was from the roll and permits it to gravitate upon theendless belt. a I

Power may be applied to the cold war;

other suitable sourceof power 4.4 (Fig. 4), the power bein transmittedtherefrom. through a short s aft 45 having a pulley 46 a pulley48'fixedly-secured to a shaft 49. Upon the shaft 49, which has bearings50 at one end'of the charging roll, is fixedly secured a worm 51 meshingwith a worm gear 52-sccured to the axle 53 of the charging roll. Inorder that there may be a fixed relation between the movement of thetrav= cling belt and the charging roll, power may be transmitted fromthe. latter to the drum 19 by means of asprocket 54 (Fig. 2) upon theend of the charging roll shaft through chain 55 and sprocket 56 upon theshaft of the drum 19; 1

The-charging roll and drum 19 may. both be mounted in a chamber 57 atthe forward end of the apparatus, and this chamber may be provided witha closure 58. through which admittance may be obtained to the chamber toinspect theworking of the charging ax may be supplied to the pan 42through a supply line 60 which leads to the pan from a reservoir 61 atthe rear end of the apparatus, and the wax in the pan may be maintainedin a fluid state by means of. a heating coil' 62 located in or designedto the pan.

In operation it will be understood that wax is conducted from thereservoir 61 to the pan beneath the charging roll where 1t is maintainedin a substantially fluid state. Rotation of the charging roll, which iscold, will cause the roll to pick upupon 1ts periphery a quantity of waxat each revolution.

.supplying roller t0 from a motor or any Wax will be removed from theroll by the scraper t3 and will gravitate upon the slowly moving belt,to be conducted through grees of temperature as it passes through thechamber. Each of these compartments is heated by the coils positionedtherein, the last compartment 10 being substantially larger than theremaining compartment, and being heated to substantially the same degreeas the compartment 10. As the wax passes throh each chamber its variousfractions, whch are suspectible to melting at the temperaturesmaintained, will drip into the receiving pans through the pertorationsin the belt. Wax may be removed from the pans in any manner, either byattaching a drain pipe, or by removing the pans at intervals, admissionbeing obtained to the compartments for this purpose by means of the[various entrances shown therein.

It is, of course, to be understood that nu merous modifications may bemade in the apparatus herein described in detail, and that thesemodifications may be made without in any way departing from the spiritor scope of the invention, which is more particularly defined in thefollowing claims.
